EMBROIDERING-MACHINE.

To all whom it may concern Bev it known that I, VICTOR KOBLER, a citizenof the Republic of Switzerland, residing at Rorschach, Switzerland, haveinvented new and useful Improvements in Embroidering-Machines; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawing, and to letters or figures of reference markedthereon, which form a part of this specification.

This invention relates to those devices which, in shuttle embroideringmachines, are employed for the purpose of reeling or wirading the fabricwhich is to be embroidere Heretofore it has been proposed to place in anembroidering machine, on the embroidery or needle side, a brake or,friction roller over which the fabric is drawn as it is wound or reeledon the roller carried by the fabric frame of the machine for the purposeof giving the fabric the desired tension and so avoiding wrinkles, and aguard rail for the row of needles, the arrangement being such that whenthe. fabric is reeled on the fabric roller it runs first, from theembroidery side of the machine, over the brake or friction roller andthence over the guard rail, from. which it passes to the fabric roller.This old arrangement has these disadvantages, namely, that the entirefront side of the machine is not kept free and unobstructed and that theguard rail must be removed before embroidering is begun.

that it does not The special purpose in view in the present case is toobviate the disadvantages which are incident to the employment 0 thearrangement just referred to and in accordance with the invention thebrake. o-r friction rollers are arranged at the back or shuttle side ofthe machine and above the rides for the shuttles, one for each story ofthe machine, so that, when the fabric is reeled on the lower fabricroller of each pair in the machine, it is guided in such a way touch theshuttle races, does the front of the machine, and fabric roller, in thefabric stretched and without wrinfabric roller to not obstruct reachesthe frame, properly kles, without requiring the v Specification ofLetters Patent.

be removed from the frame. The brake or friction rollers areconveniently mounted on pivoted armsso that the rollers can be read- 1lyturned back out of the way before embroidering begins. 7

One convenient tion is shown, by way of illustration, accompanyingdrawing in whic Figure 1 is a view in vertical section of anembro-idering machine which is equippe with fabric rolling devices. inaccordance wit-h this invention, thoseparts of the maembodiment of theinvenin the chine of which illustration 1sn0t necessary to theunderstandingof the invention belng omitted and the tops of thesideframes being broken off. Figs. 2, 3 and 4 are detail views of partsof the improved mechanism to be referred to. g The embroidering machine,except so far as the present invention is concerned, may be constructedin any usual or desired manner. It is shown in the drawing as as usual,at least two stories. It is provided with the usual supporting rails orbars '1 1 at the front or needle side of the machine, one above another,and with the usual supporting rails or bars 2 2 at the rear or shuttleside of the machine. The fabric frame 3, on which the fabric to beembroidered is stretched while it is being embroidered, is provided withpairs of fabric rollers, 4: and 5,one pair for each story of themachine. The fabric frame may be supported, during the operation ofembroidering, by means of rods 6, one of which is indicated by brokenlines in Fig. 1, such rods being remove during the reeling of the ricrollers 5. I

On each of the rear members or rails 2 of the machine are pivoted arms 7which carry a brake or'friction roller 8, such as the usual emerycovered roller, the arms 7 and roller 8 of the upperstory of the machinebeing shown in Fig. 1 as swung forward into thev position which theyoccupy during the reelf the fabric, while the arms 7 and roller 8 of thelower story are shown as swung back, out Of the way, tion which theyoccupy when embroidering is proceeding. Loosely supported by each rail 2is a board or support ports the fabric during the reeling operation sothat it may be conveniently drawn over the friction roller. As soon asthe fabric has been secured to the fabric roller, it is hav ng,

fabric on the fabinto the posi- 9 which supter. As shown in Fig.

allowedto hang over the edge of the board or support, as indicated inFig. 1. It will be observed that the arms 7 are of such length that whenthe roller 8 is supported thereby in position for the reeling operation,

the fabric 11 does not touch the shuttle races 0 as it passes to thefabric roller 5.

Each guide roller 8, which is a friction roller, being preferably theusual emery covered roller, is mounted to rotate in the arms '5 and inorder that the tensioning action of the roller 8 upon the fabric, whileit is being reeled onthe fabric roller 5 may be regulated, there areprovided means for exerting a braking action on the roller. Such meansmay be of any suitable charac- 4L they may consist of two braking arms12, pivotally mounted on the adjacent arm- 7 and held in frictionalengagement with the shaft of the roller 8 by wing-nut 13 and bolt 14, aspring 15 being preferably interposed between the wing-nut 13 and theadjacent brake mem ber'so as to permit the yielding action. "When fabricis to be reeled or wound on the" fabric rollers 5, or either of them,the supporting rods 6' are removed: and the fabric is laid from the rearover the brake or friction roller 8, is carried downward to thecorresponding fabric roller 5 and is secured thereto, the brake orfriction roller 8 having been swung forward into the position shown inthe upper part of Fig. l. The roller" 5' is th'enrotated, as usual, towind or reel the fabric thereon, the dragging action of the roller 8,under the influence of the brake, creating the necessary tension andpreventing the wrinkling and slipping of the fabric.

The brake or friction roller ordinary emery covered roller, as indicatedin Fig. 2, or it may have a roughened sheet metal covering as indicatedat 16 in Fig. 3, or be otherwise provided with the necessary roughenedsurface.
